吴雪军, 何孜成, 张玉浩, et al. 微生物强化不同基质垂直流人工湿地处理模拟初期雨水TN、NH3-N试验研究[J]. 2024, 16(3): 71-78+97. DOI: 10.16056/j.2096-7705.2024.03.011.
针对砂石基质垂直流人工湿地处理初期雨水时,存在TN和NH

-N去除效率低的问题,构建了砂石、沸石基质的垂直流人工湿地系统,接种驯化后的活性污泥,重点关注微生物强化不同基质的垂直流人工湿地处理模拟初期雨水TN、NH

-N的去除效果,并探究微生物强化人工湿地的微生物群落结构。试验结果表明:采用沸石作为湿地基质的人工湿地脱氮能力强,在接种污泥后,砂石基质的人工湿地对总氮、氨氮的平均去除率分别为63.63%~75.09%、56.49%~72.18%,其平均出水质量浓度为3.76~5.36、2.83~4.57 mg/L。接种污泥后的湿地系统内微生物群落具有较高的多样性和相对丰度。反硝化菌门(Patescibacteria)在湿地系统中具有较高的丰度,有助于提高人工湿地系统的脱氮功能。
